I believe the correct phasing you're looking for is "Garmon wanted playing time in an offense that is not equivalent to what he leaves in the toilet bowl each morning, and was stuck in such an offense that was equivalent to what he leaves in the toilet bowl each monrning."

"Running backs leave Iowa and they either succeed or they fall off the face of the earth. However, the only thing that remains common is that Iowa can’t keep them to save their lives." - RantSports article

It seems pretty clear, based on a decade of data collection that, once touched by the Hawkeye, you take your chances wherever you go if you're an RB. Garmon is surely embarking on a perilous life quest. Garmon should perhaps see himself as lucky that AIRBHG only planted in his mind the idea to transfer and seek fortunes elsewhere...for the time being anyway.

That being said, he is pretty talented and looked good in limited action but ended up behind Weisman and Bullock, so I wonder if it is a playing time issue or a foreseen lack thereof.
